Electro-hydraulic Drum Brakes

I. Basic composition of models
The model of electro-hydraulic drum brake usually consists of the following parts: brake type, braking torque, brake size, electromagnetic coil voltage, etc. The following are analyzed one by one.
1. Brake type

Brake type indicates brake structure, which is generally represented by characters, such as G, TB, YW, etc. For example, G stands for hydraulic brake, TB stands for hydraulic drum brake and YW stands for electromagnetic brake.

2. Braking torque
Braking torque is one of the brake performance parameters, and it is the magnitude of braking torque. Generally expressed by numbers, the unit is N.m or kN.m, and the braking torque usually selected is greater than the actual load torque. For example, the braking torque of 100 represents that the braking torque of the brake is 100N.m or 0.1kN.m.

3. Brake size
Brake size is not only the hole spacing of brake installation, but also one of the key technical parameters of brake. Generally expressed by numbers, the unit is mm. For example, the brake size of 200 represents that the mounting hole spacing of the brake is 200 mm..

4. Electromagnetic coil voltage
The voltage of the electromagnetic coil represents the rated voltage of the brake electromagnetic coil, which is generally expressed in numbers and the unit is V. For example, the solenoid voltage of 220V represents that the rated voltage of the brake solenoid is 220V.
Second, the model selection and application
When selecting and applying the electro-hydraulic drum brake, it is necessary to choose the appropriate model according to the specific working environment and load characteristics. Among them, the brake torque is a very critical parameter, which is generally selected according to the actual working conditions, and the technical parameters such as the installation size and voltage of the brake should be fully considered.

When using the electro-hydraulic drum brake, you should also pay attention to the following points:
1. The installation requirements of the brake meet the requirements, and the brake is firmly fixed to avoid the failure caused by the looseness of the brake.
2. The brakes should be inspected and maintained regularly, and the worn brake pads should be replaced in time to ensure the normal service life of the brakes.
3. When the machine is stopped, attention should be paid to power off in time to prevent the leakage of the electrical system and the electromagnetic brake from being energized for a long time to cause damage to the electromagnetic coil.
In a word, the electro-hydraulic drum brake is an indispensable part of the electric drive system. Correct selection and application of brake models and reasonable maintenance of brakes can ensure the stable operation and work efficiency of the machine.
